[BUG] Numbed keys are not recognized when kakoune is used in alacritty v13

[6he]

Version of Kakoune

v2023.08.05

Reproducer

Open kakoune in alacritty v13 go in insert mode and enter a numer on the numpad.

Outcome

Placeholders are displayed instead of the numbers entered on the numpad.

Expectations

The numbers entered on the numpad should be displayed.

Additional information

• When using kakoune with alacrity v12 the bug does not happen.
• I tested neovim with alacritty v13. neovim displays the numbers correctly. So it seems the bug is on the kakoune side.
• As a workaround for the numbers on the keypad you can put the following in your alacritty.toml:

[keyboard]
bindings = [
 { key = "1", mods = "None", chars = "1" },
 { key = "2", mods = "None", chars = "2" },
 { key = "3", mods = "None", chars = "3" },
 { key = "4", mods = "None", chars = "4" },
 { key = "5", mods = "None", chars = "5" },
 { key = "6", mods = "None", chars = "6" },
 { key = "7", mods = "None", chars = "7" },
 { key = "8", mods = "None", chars = "8" },
 { key = "9", mods = "None", chars = "9" },
 { key = "0", mods = "None", chars = "0" },
]

I switched to KDE with Wayland and the bug does not occur there. It seems it's a problem related to X.
As far as I'm concerned the bug can be closed.
